Microelectrodes can be used for direct measurement of electrical signals in the brain or heart. These applications require soft materials, however. With existing methods, attaching electrodes to such materials poses significant ...

Researchers in Japan used state-of-the-art micro-sculpting techniques on a new type of resin that can be molded into complex, highly conductive 3-D structures (in this case the famous "Stanford bunny") with features just ...

How active a living cell is can be seen by its oxygen consumption. The method for determining this consumption has now been significantly improved by chemists in Bochum. The problem up to now was that the measuring electrode ...

For several decades antimony electrodes have been used to measure the acidity/basicity – and so to determine the pH value. Unfortunately, they allow for measuring pH changes of solutions only at a certain distance from ...

(Phys.org)—Our brains are constantly awash in chemicals that serve as messengers, transporting signals from one neuron to another. It's a really nifty system, although scientists still aren't clear on how, exactly, those ...

Researchers from North Carolina State University have developed a faster, easier way to create microelectrodes, for use in microfluidic devices, by using liquid metal. Microfluidic devices manipulate small amounts of fluid ...

ANN ARBOR, Mich.---Brain implants that can more clearly record signals from surrounding neurons in rats have been created at the University of Michigan. The findings could eventually lead to more effective treatment of neurological ...

(PhysOrg.com) -- Many bacteria are able to 'swim' through liquids by means of a flagellum. When doing this, some bacteria follow attractants, some flee from harmful substances, and others align themselves using light, gravity, ...

(PhysOrg.com) -- Biomedical and materials engineers at the University of Michigan have developed a nanotech coating for brain implants that helps the devices operate longer and could improve treatment for deafness, paralysis, ...

Electrode

An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte or a vacuum). The word was coined by the scientist Michael Faraday from the Greek words elektron (meaning amber, from which the word electricity is derived) and hodos, a way.
